Answer:
b = 40
Step-by-step explanation:
-b/4 = - 10 Multiply both sides by 4
-b/4 * 4 = - 10 * 4
- b = - 40 Multiply both sides by -1
(-1) * (-b) = (-40)(-1)
b = 40
10 Willie and two of his friends earn money mowing lawns in their neighborhood. On Saturday,
they mowed two lawns and were paid $28. If Willie and his friends split the earnings equally,
which expression does NOT equal how much Willie will receive from working on Saturday?
The requried expression that represents the earnings received by willie is 3x = 28.
AS mentioned in the question, they mowed two lawns and were paid $28. Willie and his friends split the earnings equally,
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
Let x be the amount received by Willie,
according to the question,
3x = 28
x = $9.33
Thus, the requried expression that represents the earnings received by willie is 3x = 28.

If y = 12 when x = –15, find y when x = 2.
Answer:
29
Step-by-step explanation:
First make an equation that shows the relationship between x and y by finding what you need to do to x to get y:
-15 + ? = 12
? = 27
so the equation is : y = x + 27
now just plug in 2 for x:
y = 2 + 27
y + 29

The units of the subway map below are in miles. Suppose the routes between stations are straight. Station F, not shown on the map, is 12 miles west and 3 miles north of Station A. What is the approximate distance between Station E and Station F?
The distance from Station E to Station F is approximately ___ miles. (Round to the nearest tenth as needed.)
Answer:
8.2 miles
Step-by-step explanation:
a²+b²=c²
-12-(-4)=-8
3-1=2
-8²+2²=68
square root of 68 is 8.24 and rounded to the nearest 10th is 8.2 miles

Raleigh went to a gaming arcade for his birthday. His parents gave him $55 to spend. He purchased $14.25 in food and drinks, and put the rest of the money on a gaming card to spend at the arcade. Each game cost $1.25. Choose which inequality represents how many games "g" he can play.
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Total amount to spend = $55
Amount of food and drinks purchased = $14.25
Amount put on gaming card = $(55 - 14.25) = $40.75
Cost per game = $1.25
Number of games (g) he can play
Number of games g:
Amount put on gaming card / cost per game
= $40.75 / $1.25
= 32.6 games
g ≤ 32

On the number line, a point was moved from -7 to -3. Which of the following problems describes this move?
-7 + 4 = -3
-7 + 3 = -4
-7 - 3 = -10
-7 - 4 = -3
Answer:
choice 1) -7 + 4 = -3
Step-by-step explanation:
Since -3--7 = 4, -3 = -7 + 4, -7 = -3-4
4 greater than -7 is 3.

Select the number line that represents all solutions of x > 13.5
Answer:
it would be the 4th one because think of x as the circle. its at 13.5, now a number to the right of the number line would be greater than 13.5. The arrow shows that x's arrow is going to the right, causing the unknown number to be greater than 13.5
Step-by-step explanation:
The number line that represents x > 13.5 is option D which states that the line is greater than 13.5 and going toward infinity.
What is a number line?A number line is a horizontal line in which we can plot any real number in it also known as the real number line.
We know when a number is strictly greater than or less than some specified value we denote them by open circles meaning the point does not include the value.
Given x > 13.5 this will be represented on a number line at 13.5 with an open circle going towards infinity.

The function represented in the table is a linear function given by y = (1/4)x + 80
What is an equation?An equation is an expression that shows the relationship between two or more number and variables.
Let y represent the pressure of the gas at x temperature.
Using the point (44, 91) and (52, 93), hence:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-91=\frac{93-91}{52-44} (x-44)\\\\y=\frac{1}{4} x+80[/tex]
